Please Help! Problem with sportman 500
#1
I did my 1000 mile maintenance. Every thing with the bike is working fine except. The clutch/ belt seem to be staying engage after the I let off of the gas.
This does not always happen, but it seems to happen more after riding. The bike creeps forward with the gas off. And when that happens you cannot get it out of
gear.
Is this a bad belt. or spring. Any help would be appreciated.

It sounds like your clutch offset is out of alighnment. You can correct it by taking off the clutch cover, remove the belt, remove the bolt from the rear clutch and slide it off. You will see a spacer washer or washers. You can adjust it by adding or removing washers. Most likely you will have to add a washer or washers. The polaris part # for the washers is 7556401. My son's 500 h.0. creeped real bad and he eventually broke the shift rod. We took the washer out and went to the local hardware store and matched it up with washers of varying thickness's. It probably won't take much to align it. It happens because your belt is not rideing down in the groove of the pulley. It is favoring one side or the other causing the belt to keep turning. It will wear the edge of your belt over time if you keep rideing it. Your dealer has a clutch offset alighnment tool that they use to measure it. If you don't feel comfortable doing it, they shouldn't charge you more than probably a half hour of labor to fix it. Their were several good posts a while back concerning this problem that probably explains it better than I'm doing. Do a search and you might find them. The only other way that I know to fix it is to loosen the motor mounts and slide the front of the engine one way or the other until it's alighned but that's another story. If you have trouble getting the clutch cover off, you may have to remove the screws that hold the floorboards to the mounts. You can than pull the floorboard away far enough to slide the clutch cover off. It sounds like a lot of work but it's really not. My 700 started doing it after it rolled down a hill a couple times and being an insurance claim the dealer re-alighned the engine. GOOD LUCK!

What you want to do is take off the belt cover, and, while in Neutral, start the engine, and give it a little gas, enough to get the belt to shift up about halfway up the front pulley or so. Let off the gas, and watch closely where the belt comes to rest into the front pulley. My guess is it will try to crowd towards the side closest to the engine. If that is the case, remove the rear pulley (just remove center bolt, and a few sharp tugs should get it off by hand) and look for a washer that was between the pulley & tranny housing. Take it to a hardware store, and get a couple more of the same size, preferrably of varying thicknesses. Now, just add washers to get the proper amount of 'offset' to the rear pulley so that the belt always wants to return to dead center of the front pulley from a shiftout. Simple trial and error.
What usually happens is as the belt/pulleys wear, the belt will sometimes try to come to rest one groove off of dead center of the front pulley. This causes friction as the belt tries to 'bottom out' yet, the grooves try to shove it agains one (usually the inner) side of the pulley. Shimming cures the problem. If the belt appears to come to rest dead center every time, you may have the bearing or sprag on the center multi-V pulley dirty or going bad. Oh, one more thing: If you remove the 4 bolts that hold down the footrest, you can get the belt cover out without removing the fenders. Makes the belt easy to inspect.

I had this happen on my 425 and it turned out to be the bushings in the front pulley were hanging up not letting it release all the way.Took it apart put in new buttons and new bushings and it worked like a new one.

[img]i/expressions/face-icon-small-happy.gif[/img] Yes, all those other posts and check this out also. The insides of some belts are not cut properly. What you look for is to see if the belt is cut so that you don't have any "half" grooves on either side. ie: one groove is 1/64 from one side and the other side has a groove 1/8 in.
this way \/\/\/\/\/ not this way \/\/\/\/\| Not the best illustration, however, this will also cause belt to hug one side and creep. Good luck.

Check the bushings on the inside & outside of the EBS oneway roller that the belt rides on in the primary clutch. I have seen the outer bushing which is brass on the later models wear quickly which allows the EBS roller to move outward an the belt to ride on top of the roller. This causes the belt to rub the inter part of the clutch. The belt is trying to pull all the time and is hard to shift. If yours is 2002 the outer will be brass. The older ones were like teflon. The dealer shows a update for the outer in the older models.
